5.1.3 Attaching the Inlet Plate Assembly
Following installation of the pump scroll to the pump frame, attach the inlet plate assembly to the pump scroll as follows:
•Place flat washer on the 5/16" x 7/8" screw.
•Position a single section of the gasket against the face of the pump scroll; align the clearance holes of the gasket with the mounting holes of the pump scroll. Loosely install one 5/16" x 7/8" screw through the gasket segment and into the top cen- ter mounting hole of the pump scroll to support the gasket.
•Interlock the remaining gasket segment to the previously installed gasket segment to complete the circular gasket.
•Orient the inlet plate assembly as shown. The 1/8" NPT plug should face directly up, and the 1" NPT plug should face directly downward. Care- fully position the top center mounting notch of the inlet plate assembly to engage the mounting screw positioned
previously.
•Install the seven remaining 5/16" x 7/8" screws through the notches in the inlet plate assembly
and into the corresponding mounting holes in the pump scroll.
•Tighten screws to complete installation of the inlet plate assembly.
•Install pressure switch in 1/8" NPT hole in top of outlet.
